Alnus glutinosa 'Imperialis'


Add to wishlist Remove from wishlist
Awesome Cutleaf Alder. This selection of this European species makes our own native Alnus rubra weep in envy. The extreme ornament of the foliage makes us weep as well but with tears of joy. Rapid growth in rich moist bottomland, slower in average settings.
